FAQs
Question: What is Ohm's Law? Answer: Ohm's Law states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points, provided the temperature remains constant.
Question: How do I apply Ohm's Law in problems? Answer: To apply Ohm's Law, use the formula V = I × R, where V is voltage, I is current, and R is resistance. Rearranging this formula helps solve for any of the three variables.
